   All SAMConnection methods that provide access to messaging operations
   return <strong><code>FALSE</code></strong> if an error occurred in processing the request.
   In addition the SAMConnection object has two properties, &quot;errno&quot;
   and &quot;error&quot;, that provide respectively the error number and
   text description of the last error to occur on the connection.
